Spirituality means different things to different people. For some, it's primarily about a belief in God and active participation in organized religion. For others, it's about non-religious experiences that help them get in touch with their spiritual selves through quiet reflection, time in nature, private prayer, yoga, or meditation. Many people identify as spiritual but not religious: With a few exceptions, the percentage of adults who identify as religious in many industrialized countries is declining, while remaining generally high in less developed nations. Even as religious affiliation decreases, though, a sense of spiritual identification could remain steady or even increase.
